<h1>OC tree properties</h1>

<p>The OC tree properties are part of the <a href="sceneObjectPropertiesDialog.htm">scene object properties </a>dialog, which is located at [Menu bar --&gt; Tools --&gt; Scene object properties]. You can also open the dialog with a double-click on an object icon in the <a href="userInterface.htm#SceneHierarchy">scene hierarchy</a>, or with a click on its <a href="userInterface.htm#toolbars">toolbar</a> button:<br>
</p>

<br>

<p>In the scene object properties dialog, click  the <strong>OC tree</strong> button to display the OC tree dialog (the <strong>OC tree</strong> button only appears if the last selection is an <a href="octrees.htm">OC tree</a>). The dialog displays the settings and parameters of the last selected OC tree:<br>

<br>

<li><strong>Voxel size</strong>: the size of the OC tree voxels. The smaller the size, the more memory will be used for the OC tree data structure.</li>

<li><strong>Insert selected visible objects</strong>: allows to insert voxels based on the selected, visible objects. Only <a href="dummies.htm">dummies</a>, <a href="shapes.htm">shapes</a>, <a href="octrees.htm">OC trees</a> and <a href="pointClouds.htm">point clouds</a> are taken into account. Select all objects you want to insert, then select last the target OC tree object.</li>

<li><strong>Subtract selected visible objects</strong>: allows to remove voxels based on the selected, visible objects. Only <a href="dummies.htm">dummies</a>, <a href="shapes.htm">shapes</a>, <a href="octrees.htm">OC trees</a> and <a href="pointClouds.htm">point clouds</a> are taken into account. Select all objects you want to insert, then select last the target OC tree object.</li>

<li><strong>Clear OC tree</strong>: removes all the voxels from the OC tree.</li>
<li><strong>Voxels have random colors</strong>: each voxel will have a random color.</li>
<li><strong>Show OC tree structure</strong>: shows the OC tree data structure, mainly for debugging purposes.</li>
<li><strong>Color is emissive</strong>: voxels will be shown in emissive colors.</li>
<li><strong>Show points instead of voxels</strong>: for OC trees containing a large amount of voxels, display can be quite slow. In that case you have the possibility to display pixel voxels, instead of cubic voxels.</li>
<li><strong>Adjust color for next insertion</strong>: allows to select a new color, which will be used for new voxel insertions.</li>
